WasmGPU.compute.kernels.argminF32¶
Summary¶
WasmGPU.compute.kernels.argminF32 finds the index/value pair for the minimum f32 element.
It is a convenience wrapper over argReduceF32(input, "argmin", opts).
Output uses the same 8-byte pair layout: value bits and index.
Use this when you need the location of the smallest value.
Syntax¶
WasmGPU.compute.kernels.argminF32(input: StorageBuffer, opts?: ArgReduceOptions): StorageBuffer
const out = wgpu.compute.kernels.argminF32(input, opts);
Parameters¶
| Name | Type | Required | Description |
|---|---|---|---|
input |
StorageBuffer |
Yes | Source float buffer. |
opts |
ArgReduceOptions |
No | Optional execution settings. |
Returns¶
StorageBuffer - 8-byte result buffer containing minimum value bits and index.
Example¶
const canvas = document.querySelector("canvas");
const wgpu = await WasmGPU.create(canvas);
const input = wgpu.compute.createStorageBuffer({ data: new Float32Array([3, -2, 1, 8]), copySrc: true });
const out = wgpu.compute.kernels.argminF32(input);
console.log(Array.from(await wgpu.compute.readback.readU32(out, 0, 2)));
